This loose-leaf book (including modelling package) focusses on the solution of engineering problems related to sedimentation and erosion in rivers, estuaries and coastal seas. The problems considered are: sedimentation (sand and mud) in navigation channels; trenches, mining pits, harbours, river reservoirs, inlets and intakes and other structures; scour and erosion near seawalls, groynes, breakwaters and dams; resuspension from dump sites; dredging aspects; engineering approaches for coastal erosion (detached breakwaters, feeder berms, reef berms). The book (about 600 pages) and models will be regularly updated.A detailed overview of mud and sand transport in rivers, estuaries and coastal seas is given. Many examples are presented and explained. The book is of interest to: coastal and harbour consultants, engineers, scientists and managers.Various simple and detailed computer programmes are included to compute transport rates and sedimentation volumes.
